Abstract (en)
[origin: WO9815670A1] According to the present invention there is now provided a body of cemented carbide or cermets coated with at least one diamond layer. The diamond layer is smooth on all sides of the body with an Ra <1 mu m. According to the present invention there is also provided a method for reactive ion etching of a diamond layer on a complex shape body where the etching is efficient at all sides of the body exposed to the plasma. The etching is made using a C1- or oxygen-containing plasma with the possibility of etching of a diamond layer covered by an outer layer of preferably a Si containing material.
